All,
If you want to use traceroute, you must explicitly set a Time-To-Live on
the encapsulated packets.
These are the OpenWRT/LEDE/Linux commands (note the second line):
ip tunnel add tunl0
ip tunnel change tunl0 mode ipip ttl 64 pmtudisc
ip link set tunl0 mtu 1480 up

I'm not sure what you mean, traceroute has ALWAYS worked for me.
